Supplier Verification 101: China + Vietnam, This October

This October, Move Supply Chain is returning to factories in China and Vietnam to verify suppliers in person, not to check a box, but to look.

This October, Move Supply Chain is returning to factories in China and Vietnam we already work with, not for content, but to verify in person what usually only gets reported to us. Here’s why that distinction matters, and what any DTC brand can start checking on its own suppliers before booking a flight.

We booked the trip. As of late August 2026, the flights, the factory visits, and the supplier meetings for October are locked in, China first, then Vietnam.

We’re not going because a factory tour photographs well. We’re going because there’s a gap that opens up in every supplier relationship the moment it stops being run in person, and that gap is where most of the risk in overseas sourcing actually lives. It doesn’t show up in a weekly status email. It doesn’t show up in a compliance certificate. It shows up later, usually during the week you can least afford it, as a missed ship date, a quality problem that somehow wasn’t caught, or a subcontractor nobody mentioned.

The Gap Between a Status Update and the Truth

Every supplier relationship starts the same way: someone visits, or at least someone talks to someone who has. There’s a real person on the other end, a real conversation, a real sense of who’s running the operation. Then the relationship settles into a rhythm of emails, invoices, and the occasional photo, and that rhythm can run for years without anyone from your side setting foot in the building again.

None of what arrives during that rhythm is necessarily false. A compliance certificate can be genuine on the day it’s issued. A capacity estimate can be an honest number from the person who gave it. A photo of a clean, orderly production line can be exactly what the camera saw. The problem isn’t that suppliers lie, most don’t. The problem is that a report only ever contains what the person writing it decided was worth including, and a lot of what actually matters to you never makes that list, because nobody on their side thinks to mention it, or because it changed after the last time anyone checked.

Teams turn over on both sides of a supplier relationship, and every turnover is a small reset. The contact who answered every question honestly during onboarding gets promoted, or leaves, and whoever replaces them inherits an account with none of the history. A second workshop gets added to handle overflow during a busy season, and it’s never disclosed unless someone happens to ask the right question at the right time. A factory that was running two shifts when you signed the contract might be running three now, or one, and there’s no invoice line item for “our actual capacity changed.” This is what remote-only oversight misses, not because anyone’s hiding something, but because distance makes it easy for small, ordinary drift to go unnoticed until it’s no longer small.

What We’re Actually Going to Verify

The lens we’re bringing to China and Vietnam this October is the same one Move Supply Chain uses whenever we run a Comprehensive Manufacturer Audit for a client, just applied here on our own initiative, on suppliers and partners we already work with, before anyone has to ask us to.

That lens comes down to four things, and none of them are exotic. We want to see whether the production capacity a factory reports actually matches what the floor can support, meaning the real line count and shift pattern, not the number in last year’s onboarding deck. We want to know who’s actually running production day to day, and whether that person is who we think it is. We want to know whether any part of the work has been quietly subcontracted to a second facility, since this is the single most common thing that never comes up unless it’s asked about directly. And we want to see whether the documentation on file, certificates, records, production logs, actually holds up against what’s physically happening in the building, rather than existing as a PDF that gets forwarded on request and never checked against anything else.

We haven’t gone yet, so we don’t have findings to share, and we’re not going to manufacture any before the trip actually happens. What we can tell you now is the standard we’re holding ourselves to: the same one we’d apply for a client, pointed at our own supplier relationships, in the open, so the process is visible instead of just claimed.

If you want the same kind of supplier verification applied to your own sourcing setup, Move Supply Chain’s Vendor Visits put our team on the ground in China and Vietnam to vet suppliers, visit factories, assess quality and capacity, and negotiate directly with suppliers on your behalf.

Why This Trip, Why Now

This is also part of why in-person supplier verification matters more right now. As of late August 2026, U.S. trade authorities have multiple Section 301 actions involving China and Vietnam. One action concerning forced labor has already reached final action, with additional tariffs taking effect on July 24 across 60 economies, including China and Vietnam. A separate Section 301 investigation into structural excess manufacturing capacity includes both countries and is still ongoing. Vietnam is also subject to a separate Section 301 investigation focused on intellectual property protection and enforcement.

The specific policy outcomes can continue to change, but the sourcing lesson is more immediate. A country that looks like a lower-risk sourcing option on paper still needs to be verified at the supplier level. That means looking beyond the country name and asking what is actually happening inside the factory: who is producing the goods, what capacity is really available, whether subcontracting is involved, and whether the documentation matches the physical operation.

That’s one reason we’re going to China and Vietnam in October. We’re not going to predict what we’ll find before we get there. We’re going to see what’s actually happening at the factory level and use those conversations and observations to understand the supplier relationships behind the paperwork.

The broader lesson is simple: moving production to a different country doesn’t automatically remove supply chain risk. It changes the questions you need to ask. The more uncertainty there is around trade, sourcing, and manufacturing, the more important it becomes to know exactly who is making your products and how that production is being managed.

A Visit Is Not the Same as an Audit

It’s worth being precise about what a trip like this actually produces, because a factory visit and a factory audit aren’t the same thing, even though they get talked about as if they are.

A visit is what happens when you walk the floor, shake hands, and leave with an impression. That impression can be genuinely useful, and it’s better than nothing, but on its own it doesn’t survive contact with a hard question later. “We went and it seemed fine” isn’t something you can hand to a bank evaluating your supply chain risk, an insurer pricing a policy, a wholesale partner doing their own diligence, or even your own team eighteen months from now when the person who took that trip has moved on and someone else needs to know what was actually checked. An audit is what turns that same visit into something durable: a dated record of what was verified, against what standard, with what evidence attached, built so it can be picked back up later by someone who wasn’t in the room.

That distinction is exactly why the trip is being treated as a verification exercise and not a highlight reel. The value isn’t in having gone. It’s in what gets documented because we went.

What You Can Check Without a Passport

None of this requires a flight to Shenzhen or Ho Chi Minh City to start, and that’s the part worth taking away even before we’ve left. The same four questions we’re bringing to China and Vietnam apply just as well to a supplier you already work with, wherever they happen to be.

Ask for current capacity numbers, not the figure from your original onboarding call, and ask how they were actually measured. Ask, by name, who your real point of contact on the production floor is today, and whether that’s changed in the last year without anyone telling you. Ask directly whether any portion of your order has been subcontracted, and to where, since this is a question most brands never think to ask at all, let alone follow up on. And ask for documentation you can actually cross-check against something else, a production record or a shipping manifest, rather than a certificate that exists mainly to be forwarded on request.

How a supplier responds to those four questions tells you almost as much as the answers themselves. A supplier confident in its own operation will usually answer directly, sometimes even volunteer more than you asked for. One that goes vague, slow, or faintly defensive is telling you something true without having to say it out loud.

If you want a practical checklist to use on your own supplier, the Comprehensive Manufacturer Audit SOP lays out the full process Move Supply Chain uses to pressure-test supplier relationships. It is free and ungated, so you can use it without filling out a form. Start with it before you book a flight, schedule your next supplier review, or approve your next production run.

Follow the Trip

We’ll be posting real updates as the China and Vietnam visits happen, not a curated recap assembled after the fact to make the trip look tidier than it was.

The best way to follow along is Unboxed Weekly, where notes from the ground will land first, while they’re still current, before anything gets smoothed into a longer piece. Supply Chain Moves will pick it up too, once there’s enough from the trip to actually discuss rather than preview.

And if reading this has already brought a specific supplier to mind, one you haven’t checked on in a while, there’s no reason to wait for October to do something about it. The Comprehensive Manufacturer Audit SOP works today, on whatever supplier relationship is sitting in the back of your mind right now.


Unit costs, freight, duties, and foreign exchange shift constantly, which means your landed cost is a dated snapshot, not a fact. When Operations and Marketing are working from different snapshots, the misalignment shows up in your promo calendar, your ad spend, and your margin — often without anyone noticing until Q4. I walk through exactly how to fix it.
